Title: Facsimile equipment
Inventor: OUE YUJI
IPC: H04N1/00
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent a fault due to voltage fluctuation in an external power supply and occurrence of a fault in the facsimile transmission reception by separating a drive power supply means from the external power supply in the case that it is detected that an input voltage is not between the lower limit voltage and the upper limit voltage. SOLUTION: In the case that an input voltage of a commercial AC power supply is faulty during facsimile reception processing, that is, the input voltage is at the outside of a range between a prescribed upper limit and a prescribed lower limit voltage, the facsimile reception processing is stopped. Then a relay RY is turned off to stop an output of a drive power supply Vd supplied from a PSU 7 to a plotter section 6. Furthermore, a system control section 2 displays a defective state of the input voltage by lighting a light emitting diode of an operation display section 8. Since the load of the PSU 7 is reduced by an amount of the drive power supply Vd to the plotter section 6 requiring much power consumption, the defect of the PSU 7 is not caused. Moreover, it is prevented that the facsimile reception processing is defective because the drive power supply Vd is unstable.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent communication between terminal equipments from being interrupted by providing an ATM exchange with a monitor means for detecting congestion of traffic or a fault and an alternative means for alternating a call to another relay line. SOLUTION: A monitor means corresponds to a UPC section 12 and a fault detection section 16, and an alternative means corresponds to an HCV section 13 and a connection management control section 18. A VPI/VCI(virtual path identifier/virtual channel identifier) conversion table 19 registers and manages for each call the usual and alternative VPI and VCI and selects an alternative relay line and sends a call therethrough on the occurrence of congestion of an active relay line. A priority condition management table 20 decides the priority when a communication call is bypassed to another relay line from the active line to bypass the call quickly.  A monitor means detects congestion of traffic when the transmission amount of the connection band of the relay line reaches a maximum prescribed ratio of the band and the call is bypassed to other relay line to prevent communication between terminal equipments from being interrupted.

Abstract: PURPOSE:To improve the reliability of a cooler for an erosion of a passage for feeding a refrigerant and easily remove dust etc. with which the passage is inside or outside by providing a feeding direction switching unit for alternately reversing the flow of the refrigerant. CONSTITUTION:A pair of heat exchangers 1 are connected through flowing direction switching units 2 to a tank 3, and the unit 2 can reverse the flowing direction of refrigerant flowing in the exchanger 1. When the refrigerant flows in a direction of an arrow 10, the inner face of a passage 9 in the exchanger 11 is eroded at a position 11 where the refrigerant collide and a position 12 where the flow of the refrigerant is largely disordered. When the refrigerant flows in a direction of an arrow 20, the inner face of the passage 9 is eroded at a position 21 where the refrigerant collides and a position 22 where the flow of the refrigerant is largely disordered. When the flowing direction of the refrigerant is alternately reversed by the unit 2, the positions to be eroded of the passage 9 are dispersed, the erosion amount per one position is reduced by half, thereby extending the life of the passage 9. If dust and the like are filled in the fins in the exchanger 1, when the flowing direction of the refrigerant in the exchanger 1 is reversed, the dusts are separated from the fins, and collected by a filter 7.
